BINDING ATTACHMENT FOR THRESHERS OR RUBBERS.

SPECIFICATION forming part of Letters Patent No. 604,319, dated May 17, 1898. Application filed May 10,1897. seriuito. 635,915. (No modem" ments for Threshers or Rubbers, of which the following is a specification, reference being had therein to the accompanying drawings.

My present invention relates to an improved binding attachment for threshing-machines, designed more especially for attachment to rye-threshers; and the object of the invention is to provide an improved form of packer-arm which will operate effectively to gather in the light straw as it comes from the apron or straw-carrier and bind it into bundles prior to its final delivery from the machine.

I have illustrated the invention in the accompanying drawings, in which only a sufiicient portion of the straw-carrier and the operating parts of the binder is shown to illustrate the invention and the operation thereof.

In the drawings, Figure 1 represents a perspective view of the binding attachment applied to the rear end of the straw-carrier of a thresher, a portion of the apron being broken away; and Fig. 2 is a detail view of one of the packer-arms.

Referring more particularly to the drawings, 3 represents the. end of the straw-carrier of a thresher of the ordinary or any desired form, and 4 the inclined binder-deck, which, in connection with the guide-arms 5, forms a hopper or straw-box to receive the straw and supply it to the binding attachment at the bottom thereof. The driving or crank shaft which operates the packer arms is shown at 6, journaled in the frame-pieces 7 and carrying cranks 6, to which the packers 8 are pivotally connected by suitable connections 9, the lower ends of the packers being connected by suitable links with a stationary part of the frame. These parts are located in rear of or beneath the inclined binder-deck, and the packers work through slots or elongated openings 4* in the binder-deck,as shown in Fig. 1, being advanced through the slots at the upper extremities thereof to grasp the straw and draw it downward and pack it into a compact bundle at the lower portion of the box preparatory to the twine being wound around the bundle.

Owing to the extreme light and feathery nature of the straw coming from a thresher it is very difficultto pack it into a bundle of sufficient size and weight to cause the tripper of the binder to loosen, and thus allow the needle to make its movement and the work of making the finished bundle to be performed. This object I effectually overcome by forming the packer-arms in'the manner shown in the drawings and more fully in detail in Fig. 2, in which it will be observed that the main or body portion of the packer-arm terminates in a tooth 8* and in rear of this tooth is provided with an angular extension 8*. This an gular extension or arm 8 carries a number of teeth, preferably two,which are preferably arranged concentric with each other, as shown at 8 and 8 In the movement of the packerarms the upper tooth catches a portion of the straw and draws it down to a position where the next tooth can take it in the next succeeding movement of the packer-arm. The second tooth draws the straw still farther down into the path of the lower tooth, which on the next forward stroke of the packer will catch and press down into the bundle the straw thus given it by the second tooth.

In order to prevent straw from dropping down behind the extension of the packer-arm after it has passed through the apron and thus being caught bythe extension on its backward movement, which would result in choking the packers and interfering with the working of the binder, a bow or curved arm 8? is provided which forms a continuous curve from the upper tooth around to where its rear end joins the body of the packer. The result of this is that while the packer is in its forward position the straw which is dropping down into the box or hopper rests upon' the upper side of this bow and slides freely off from the same on the backward movement of the packer.

Having thus described my invention, what I claim is 1. In a binding attachment for threshers or rubbers a packer comprising the body portion, the extension carried thereby having a plurality of teeth, and a curved guard extending from the extremity of said extension extension of the outermost tooth, substan- 1o tially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
